T0 all whom it nea/y concern,.-

Be it known that I, LESTER L. SIDWELL, a citizen of the United States,residing at Rivera, county of Los Angeles, State of California, haveinvented and discovered a new and useful Improvement in VVeeders andCultivators; andl do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to improvements in weeders and cultivators; andthe objects of my improvement are, first, to construct a frame havingweed-cutting blades and earth lightening and turning blades securedthereto; second, to make the weed-cutting and earth-turning blades withdevices in order to adjust them upon the frame, and, third. to providethe said blades with means whereby the blades can be removed from theframe, the said 'blades turned or twisted upon themselves.

The invention consists, essentially, in the construction, combination,and arrangement of the several parts, as will be hereinafterY fullydescribed in the specification, shown upon the drawings appended hereto,and specifically pointed out in the claims made a part hereof.

I attain these objects by the construction, combination, and arrangementof the several parts illustrated upon the accompanying drawings, inwhich Figure l is a plan view of my improved weeder and cultivator. Fig.2 is a view in cross-section taken on the line a a of Fig. 1 looking inthe direction of the arrow. Fig. 3 is a side elevation of a portion ofone of the runners, parts thereof broken away, a weedcutting bladesecured to the runner, and a portion of the brace in cross-section. Fig.4 is a plan View of one of the runners having one of the weed-cuttingblades fastened thereto, parts of the runner, blade, and the brace 'forthe frame broken away. Fig. 5 is a plan View of one of the weed-cuttingblades. Fig. 6 is a view in elevation of one of the weed-cutting blades.Fig. 7 is a view in elevation of aportion of one of the runners havingone of the earth-cutting' blades secured thereto, a portion of the saidrunner broken away and the end brace shown in cross-section; and Fig. 8is an end view of one of the runners having one of the earth-cutting'knives secured thereto and a portion of the end brace shown inelevation.

Similar reference letters, numerals, and

characters refer to like parts throughout the several views.

The reference-letter A denotes the frame of my improved weeder andcultivator. The reference-numerals l 1 indicate the double centralrunner, the numerals 2 2' designate the double runner on one side of thesaid central runner l 1', and the numerals 3 3' indicate the doublerunner on the opposite side of the said double central runner. Thenumerals 4 4 and 5 5/ refer to the outside double side runners, which,like the said double runners, when bolted together with thecutting-blades and knives between them brace and firmly hold the saidblades and knives in the desired positions. All of the said runners areconstructed substantially alike, and the detailed description herein ofone of the said runners will answer for the description of all of them.

The reference-numeral 6 denotes the front brace of the weeder andcultivator, and the numeral 7 the rear brace thereof. The said braces 6and 7 are secured to the upper edges of each of the said runners bymeans of screws 7 7', screw-threaded bolts and nuts, or equivaientdevices, the said braces serving to retain the double runners parallelto each other.

I prefer to make my improved weeder and cultivator with five doublerunners. I may, however, constructthem with any number of runnersdesirable.

The said double central runner l 1', hereinbefore mentioned, is made byplacing the fiat sides or faces of the two members 1 1 approximatelytogether and parallel with each other, leaving a narrow space 9 betweensaid members, in which space the ends 10 10 of the weed-cutting blades12 12 are secured by means of screw-threaded bolts and nuts 13 13 and 1414, respectively, or equivalent devices.

The weed-cutting blades 12 12 near the ends lO 10 thereof are providedwith elongated slots 8 8, having communicating recesses 8 8, in whichthe pins 14 14', connecting the adjacent members of each of saidrunners, are adjusted in order that the cutting-blades 12 12 can beraised or lowered to make a deep or shallow cut in the earth, as maybe.desirable, and, furthermore, to facilitate the removal of the saidcutting-blades from the runners whenever required to sharpen the sameand to provide for readily and easily cutting weeds below the surface ofthe ground and at the same time for lightening and turning up largeareas of the earths surface. Connecting also the said members of each ofthe said runners are lOO IlO

bearing-pins 15 15, (shown upon Figs. 3 and 7 of the drawings,) againstwhich the rear edges of the ends 10 of the cutting-blades 12 andthe rearedges of the cutting-knives 20 2O bear when the said blades and knivesare in operative positions.

The blades are given in their construction about a quarter-turn uponthemselves in order that when the ends of the blades are secured betweenthe said membersv of the runners, as above described, the cutting edge10 of the portion 1() is slightly inclined downward into the earth', andthe curve 10" permits the loosened earth in large quantities and withthe least possible resistance to pass over the cutting portion 10' ofthe blade in the rear thereof.-

The earth-cutting knives 20 2O I preferably secure to the rear ends ofthe runners 2 2', and 3 3 are provided in a similar manner withelongated slots 8 8, connecting recesses 8 8", and with connecting-pins14' 14' and bearingpins 15 15, on which the said knives can be adjustedand on which pins' the said knives bear when in operative position. rlherear edges of the knives 2O 2O rest against the bearing-pins 15 15(illustrated upon Fig. 7 of the drawings) when the said weeder andcultivator is being Worked.

The front ends of the side runners 4 4 and 5 5 are provided with staples25 25, in which the rings 26 26 or equivalent devices areconnected. Thesaid rings are connectedl at one end with chains 27 27, and the oppositeends of the chains are connected with the ring 28, secured to a staple29, inserted into the Whiii'letree 30' or other equivalent device towhich draft is applied for moving the weeder and cultivator..

-1t will readily appear from the foregoing description, when read inconnection with the drawings hereto appended and made a part of thespecilication and claims, what is the operation of my improved weederand cultivator, and further description of the mode of operating thesame is deemed unnecessary.

It is obvious that many variations and changes in the details ofconstruction, combination, and arrangement of the parts of my inventionwill readily suggest themselves to persons skilled in the art and stillbe Within the spirit and scope of my improvement.

I do not desire to confine this invention to the specific constructionand arrangement of parts herein shown and described, and the right isreserved to make all changes inand modiiications of the same that comewithin the spirit of this invention; but I do desire to secure as myinvention all features of construetion and equivalents thereof that comewithin the scope of my improvement as herein shown and described, andillustrated upon the draw- .ings appended hereto.

Having described my invention, what I do claim, and desire to secure byLetters Patent,

1.- The weeder and cultivator comprising a double runner, theweed-cutting blade having in` one end thereof an elongated slot providedwith recesses communicating with said slot, a pin adapted to be operatedin said slot and recesses whereby the blade can be adjusted relative tothe runner.

2. The weeder and cultivator comprising double runners, means forconnecting the runners together, the cutting-blades and earthcuttingknives, provided in the ends thereof with elongatedv slots havingcommunicating recesses, means for ad j-ustably securing the cuttingblades and knives between the members of the runners relative to therunners.

The weeder and cultivator comprising a series of double runners,meansfor connecting th'e runners together, cutting-blades secured between themembers of the double runners, said blades having slots near the endsthereof and provided with recesses communicating with said slots, pinsadapted to operate in said slots and bearing-pins against which the saidblades are adapted to press when in operative position.

4. A cultivator comprising double runners, weed-cutting blades,havingthe portion 10 and the portion 10', the latter portion twisted or turnedupon the former portion 10, at an angle thereto,the said portion 10 ofthe blades provided with an elongated slot having recesses above andbelow the said slot communicating therewith, a pin secured to therunners adapted to be operated in said slots and recesses of the bladesfor adjusting the said cutting-blades upon the runners and bearing-pinsconnected to the runners against which the rear edges of the blades areadapted to bear when the blades are in operative position.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
